This project, funded by the Mellon Foundation, sought to use the power of library licensing agreements to effect change in third-party platform practices in order to bring them into alignment with library values of privacy, confidentiality, and respect for user control over their own data. It reflects an identified Pathway for Action from the IMLS-supported National Web Privacy Forum. The goal was to develop model license language on user privacy that would support libraries in advocating for user privacy when contracting for services and content. By ensuring that user privacy is contractually protected in licensing agreements, service contracts, etc., libraries would be able to hold platforms accountable for their data practices.
